1. What is the Car Loan Interest Rate Calculator?

The Car Loan Interest Rate Calculator helps you determine the annual interest rate on your car loan based on the compound interest formula. It's particularly useful for comparing different loan offers and understanding the true cost of borrowing for your vehicle purchase in Australia.

2. How Does the Calculator Work?

The calculator uses the compound interest rate formula:

\[ R = n \times \left( \left( \frac{A}{P} \right)^{\frac{1}{n \times T}} - 1 \right) \times 100 \]

Where:

\( R \) — Annual interest rate (%)
\( A \) — Final amount including interest (AUD)
\( P \) — Principal loan amount (AUD)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: This formula calculates the effective annual interest rate by considering how often the interest is compounded throughout the year.
